When Bai Zemin's body stepped through the open doors of the first silver pagoda, he immediately felt as if he was stepping through some kind of invisible membrane. Although it was only one step, the unspeakable feeling made him feel slightly uncomfortable for a mere fraction of a second before that feeling of discomfort disappeared without a trace.
However, Bai Zemin did not expect to encounter something so miraculous when he stepped into the pagoda so when he finally saw what lay beyond that strange darkness that even the sun's rays could not pierce he stood there frozen.
His reaction was by no means special since Shangguan Bing Xue and Chen He also froze when they entered the building moments after him. The same happened to Sun Ling, Xia Ya, Wu Yijun, Huang Tian, Liang Jing, Teng Hua, and all the others who entered the pagoda not long after.
